Hi, I'm using the win32 raw mouse input within the window messageProc, so when it receives the WM_INPUT message I then set my mouseX and mouseY values. My problem is that those values are only set when the mouse is moved, so that they aren't set to 0 when the mouse isn't moving. This is causing problems with my mouse look, making it drift around the place. I tried setting a mouseMoved flag to true when the mouseX and mouseY variables are set, and then in my main loop I am doing this:

while(1) {
   runWindowMessages();

   runGameCodeIncludingMouseLook();

   if(!mouseMoved) {
       mouseX=mouseY=0;
   }
   mouseMoved = false;
}

But this just makes things jerky, since when the mouseX and mouseY are sampled, most of the time they are getting (0,0). (This is with vsync off btw.) Thanks.

I do it like this:

Works like a charm.

Edit:
Oh wait, mouse look
Then you should do it like this:

Get the mouse coords from a variable that is updated in message cycleSnap mouse to the middle of the screenSubtract screen center coordinates from previously retrieved ones
